Which of the following statements accurately describes the difference between heat stroke and heat exhaustion?

A. Heat stroke is caused by low sodium intake, while heat exhaustion is caused by prolonged exposure to high temperatures: Both are caused by prolonged heat exposure. While low sodium may contribute to heat cramps, this explanation does not define the difference between the two. B. Heat stroke is characterized by profuse sweating, while heat exhaustion is characterized by a lack of sweating: This is reversed. In heat exhaustion, the person sweats heavily. In heat stroke, the person stops sweating as the thermoregulatory system fails. C. Heat stroke is more severe and can lead to the cessation of sweating due to the body's inability to regulate temperature effectively. Heat exhaustion is characterized by excessive sweating, weakness, and fatigue: Heat stroke is a medical emergency with high core temperature and absent sweating; heat exhaustion is less severe with heavy sweating, dizziness, and fatigue. D. Heat stroke and heat exhaustion are interchangeable terms that describe the same condition: They are distinct clinical conditions with different severity and management approaches.
